434 CHAPTER 24 MAC OS X DEVELOPMENT: THE APPLICATION FRAMEWORKS Spotlight has built-in support for most common data types, such as JPEG and PDF. If your application produces standard data, you don’t need to do anything to take advantage of Spotlight. If, however, you’re using a custom data type, you’re going to need to provide a custom importer. Spotlight importers are plug-ins that Spotlight uses to translate custom data types to the metadata it needs to work its magic. By providing an importer, you not only ensure users can find their stuff, but you also get to participate in Spotlight-based features like the Finder’s smart folders, shown in Figure 24-12. Figure 24-12. Spotlight’s smart folders in the Finder Fortunately, it behooves Apple to make providing an importer as painless as possible, so Xcode includes the Spotlight Plug-in template to get you started. There’s also a Core Data template that includes a Spotlight importer. From within your application, you can offer users a standard Spotlight interface. You can also query Spotlight’s metadata database programmatically. Spotlight offers an Objective-C interface for building and executing object-oriented queries based on the NSPredicate class used throughout Cocoa. You can also set things like sort order, grouping, and whether you want to receive live updates if anything changes behind your back. NOTE For more information about Spotlight, see Chapter 3. Quick Look Quick Look provides rich previews of files, using a plug-in system similar to Spotlight. Known file types have plug-ins already installed, but custom types must provide a simple thumbnail and an extended preview. Users can then examine the file visually, even if the application used to create it no longer exists on the system. Quick Look uses a two-level preview system. Documents can provide a thumbnail, which is a simple visual representation of the data. Often, this is just a static image stored in the document bundle. Once the thumbnail is loaded, Quick Look may present a preview. Unlike the static
CHAPTER 24 MAC OS X DEVELOPMENT: THE APPLICATION FRAMEWORKS 435 thumbnail, the preview can be nearly anything. Your preview might be your entire document as a PDF, or perhaps a QuickTime movie of your application in action. You can even generate dynamic content on the fly. Quick Look is a good chance for your documents to shine, but if you do not provide a preview, users will get disappointing generic icons, like the white document icons to the right of center in Figure 24-13. Not only is Quick Look used in the Finder’s column and Cover Flow views, it can also be activated by users directly. Figure 24-13. Spotlight’s smart folders in the Finder, enhanced by Quick Look and Cover Flow Scripting Bridge The best way to integrate with other applications is through an official API, but when that nicety is not afforded to you, you can always use AppleScript. As discussed in the last chapter, Apple- Script is the high-level language users can use to make applications do their bidding. Unfortunately, AppleScript is not particularly fast. Using it in your application, while certainly possible, requires you to shift your brain mid-project into another language. When performance is a factor, developers have traditionally turned to Apple Events, the low-level system that lets AppleScript work its magic. Somewhere on Earth I’m sure someone understands Apple Events, but by now you should know Cocoa programmers hate resorting to low-level programming. Apple, in its inimitable way, has simultaneously solved all these problems at once with Leopard’s new Scripting Bridge. Using Scripting Bridge is so easy it almost defies explanation: 1. Run the command-line tools sdef and sdp to generate Objective-C headers from another application’s AppleScript dictionary. 2. Include the generated headers in your project. 3. There is no step 3.
